The invention discloses a three-dimensional super-resolution method based on disparity map fusing, and relates to the field of computer vision. The phase correlation algorithm is introduced into the method; a binocular camera shooting unit is transversely moved to obtain a plurality of depth maps in one scene, translation parameters of pixels of the depth maps and a standard depth map are calculated through the adoption of phase correlation characters, the pixels in the depth maps are inserted into the standard depth map one by one according to the translation parameters, and the depth maps are projected to three-dimensional space through camera parameters corresponding to the standard depth map; finally, super-resolution three-dimensional reconstruction results are obtained. The problem that when a binocular three-dimensional reconstruction system is actually applied, as the resolution ratio of an image collecting device is low and the signal to noise ratio is small, the resolution ratio of the three-dimensional reconstruction results is small is solved.
